Public Member Functions
	SharedPtr (ObjectBase *obj) noexcept
	Put an object that is derived from ObjectBase under the control of the smart pointer class.
	SharedPtr (T *obj, void(*deleter)(void *)) noexcept
	Put an object under the control of the smart pointer class with the corresponding deleter function pointer.
	SharedPtr (const SharedPtr &ref) noexcept
SharedPtr &	operator= (const SharedPtr &h)
void	reset () noexcept
	reset shared pointer and delete controlled object if necessary
void	reset (ObjectBase *obj) noexcept
	put a new ObjectBase object under the shared pointer control
void	reset (T *obj, void(*deleter)(void *)) noexcept
	put a new object under the shared pointer control (with the corresponding deleter function pointer)
void	swap (SharedPtr &h) noexcept
T *	get () const noexcept
	get pointer to controlled object
const T &	operator* () const
T &	operator* ()
const T *	operator-> () const
T *	operator-> ()
unsigned int	use_count () const noexcept
	get number of SharedPtr instances that reference the same object
bool	unique () const noexcept
	is the controlled object only referenced by this SharedPtr instance
	operator bool () const noexcept
T *	release ()
	release the controlled object This is only possible if the controlled object is only referenced by the current SharedPtr instance. The user has to take care of deleting the object.

Detailed Description

template<typename T>
class opals::SharedPtr< T >

smart pointer class for opals objects

Smart pointers uses a reference counting mechanism to control the life time of an object. When the last SharePtr instance goes out of scope, the controlled object is deleted. In case an object is shared across dll boundaries, it is essential create and delete objects within the same heap. To do so you can either provide a corresponding delete function (only non-member functions are supported) or an object is derived from ObjectBase and the (overloaded) Delete function is called to delete the object.
